Abstract
A slot antenna formed in combination with a vehicle window. An electrically conducting, optically transparent film panel is bonded to the window and terminates so that its outer peripheral edge is spaced from the innermost edge of the metal framing the window to define a polygonal antenna slot between the edges. An unbalanced transmission line is connected to the antenna by connecting the grounded conductor to the framing metal near the metal edge and coupling the ungrounded conductor to the conductive panel near the juxtaposed, interfacing edge of the conductive panel.
